TO ALLVHOM IT MAY CONCERN: Be it known that we, E.' A. MLLER. 'and THEODpR STOCK, of Chicago, in the county ot" Cook', and .State of Illinois, have invented a new and-,improved Doubler for Stills; and we do hereby declare that the-following is a full, clear, and exact description thereof, which vill enable others skilled in the art to make and use the same, reference benghad tothe accompanying drawing, forming part of this specification.`

llleidrawing represents a vert-icalcentral section of ou`1` improved doubler. v

AThis invention relates to a new apparatus for reetifying spirits on their passage from the still to the cooling-worm. i A

The object of theinvvention is to so construct a rectifier or doubler that thepioeess of distillation may be quickly carried on', that directly from the mash pure spirits may beproduced, and thatthediiferent grades oi liquor may be Well separated from each other.

'The invention consists in the .use of an upright cylinder, closed atbotli ends, and provided within its interior with a series of pans and abutting plates, by means of which the aseeriding vapors will be detained, and the Y products ot' condensationarrested', so thatthe lower degrees ofspirits will be separated fromrthe iner,while the pure alcoholic vapors are allowed toescape to the cooler, andthe low-Wines reconducted to the mash.

The invention also consists in arranging, around the outside offthe cylinder, annular' cooling-vessels, which communicate with each other and with. the dish-shapedover of the cylinder, by means of pipes, so that cooling liquid, poured upon the cover, will gradually find its way to the lower annular pan, so as to have passed along the entire height of the cylinder.

A, in the drawing, represents an upright sheet-metal or other cyl'indei-,-constructed of one piece, or of two or more;v In the latter oase the various sections are rmlyxunited, so that one complete air and watertight cylinder is produced.

The cylinder is provided with a bottom-plate, B, and if desired, with a removable covering-plate, C, the

latter being set below the upper edge of the cylinder, so as to forni a dish, as shown. Thercovering-plate C is somewhat higher in thc centre than at the edges, so that any liquid poured upon it'may flow towards the edges, whence it is conducted to the outside through a pipe, a. l

Around the outside of theV cylinder is arranged a series of annular pans orrvessels, D D, into the upper most of which the liquid flowing from the cover C is conducted. The vessels D D communicate vit-h euch-other by means of pipesbl, as shown. The lowermost vessel,-D, has a pipe, c, through which its contents may b e carried off to a suitable receptacle.v I

The coolingliquid, for producingthe condensation of .the `low-wines, is pouredJupon theplate (Land then I 'gradually Howsdown from'vessel to-vessel D. As the vessels D are so arranged that their inner. walls are formed by the outside of the, cylinder A, the walls ofthe cylinder will be cooled by the` lilluid in the vessels.

The vapors are conducted 'from the still to the bottom or lower part of the cylinder A, in` a pipe, d, and another pipe, e, entering the lower part of the cylinder, serves toxcarry oli' the low-wines. t

Within the cylinder A is arranged a series of'dishes, E-E, perforated plates F F, andv combined plates and dishes G. The dishes E are horizontah plates, with adepression in the centre for retaining liquid matter. The diameter of these dishes is smaller than that of the cylinder, as shown, so that a space is left between them to allow the vapors to pass upward. i'lhe dishes E are supported vby brackets or legs ff, as indicated. The plates F F itv close within the cylinder A, and ,are perforated in the middle, so thatthe vapors can pass upwards through them. i

The combined plate and dish `Gr is asmall dish, g, suspended, by means of pins h 71, from a plate,z', the latter being perforated in the middle, and'tted `close within the cylinder, as showna The vapors, which ent-cr the cylinder A, through the pipe d, strike against the lower sides of thedishes E and plates F, and are detained thereby suiciently long to allovv the condensation of the impure parts. The low-wines drop from the lower dish E and plate F upon the bottom, B, of the vessellA, and are carried back to.

aud platesG, all made and operating substantially as hereiushownand described.

the still by the pipe e. Whatever drops oi the under sidesoi the upper'dishes Eef plates F- is caught in the dishes E, and retained therein. 'The vapors have to pass iu a zigzag line `around the dishes E, and througlrthe plates F. Striking against thebottom of a plate, z',' theirnpurfe vapors arecondensed and dropinto Ythe dish g, while what condenses directly above the plate is retained on the-same, its oeutral perforation being guarded by a short pipe, j,. a s shown. Those vapors which nre n ot condensed in the, apparatus escape from the upper part of the same through a pipe, k'.

i This apparatus may be made o f suitable size, according to the 'size of the still,- and to the quantity of liquor to be distilled. .The number Yof plates and dishes'E F G in its interiorpand of vesselsV D D around' itsoutsille, can be varied at pleasuee. l Y

We claim as new, and'desire to secure by Letters Patent* 1. .Arranging around the outside of a rectifier or Idoubler, A, a series of annular cooling-vessels, D D, which communicate with the upper part of the vvessel A, jsubstantially as and for the purpose herein-shown and described.'
